Precision Twist Drill 6000434 Extra Length Drill Bit

Product Description

The PRECISION TWIST DRILL 6000434 is a high speed steel extra length drill bit designed for deep-hole drilling in metalworking and fabrication applications. The 5/16-inch diameter, straight-cylindrical shank bit measures 18 inches in overall length with a 13-inch spiral flute, giving technicians and machinists the reach needed for deep holes that standard-length bits cannot access. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The bright uncoated finish is suited for use with cutting fluids and is compatible with a wide range of workpiece materials. Right-hand cutting direction follows conventional drill press and hand-held power tool setups.

This bit is built for professional shop use, production drilling, and field fabrication where extended reach is required. It performs in aluminum, magnesium, copper, nickel, synthetic materials, and titanium as primary workpiece materials. Secondary applications include stainless steel, nickel alloy, malleable iron, hardened steel, high strength bronze, reinforced plastics, and steel. It fits standard drill chucks accepting a 5/16-inch straight shank and is appropriate for machine shop technicians, pipefitters, ironworkers, and industrial maintenance professionals who need consistent performance in deep-bore situations.

Key Features

• 18-inch overall length with 13-inch flute for deep-hole reach beyond standard bit capability
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• High speed steel construction for durability across a broad range of metallic and synthetic materials
• Bright uncoated finish compatible with water-soluble and oil-based cutting fluids
• Two-flute regular spiral design promotes chip removal in deep-hole drilling operations
• Meets ANSI standards for general-purpose drill bit geometry and tolerance

Compatibility

Designed as a general-purpose extra length drill bit for use in standard drill presses, CNC drilling equipment, and hand-held power tools accepting a 5/16-inch straight-cylindrical shank. Primary workpiece materials include aluminum, magnesium, copper, nickel, synthetic materials, and titanium. Secondary workpiece materials include hardened steel, high strength bronze, magnesium alloy, malleable iron, nickel alloy, reinforced plastic materials, stainless steel, and steel.

Installation Notes

Secure the shank fully in the drill chuck and verify runout before beginning a cut. Power down and lock out the machine before changing bits or clearing chips from the flutes. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not exceed the recommended feed rate or spindle speed for the workpiece material and bit diameter.
